When you read the article, all kinds of statements are made that could reflect in the article having Wikipedia categories. In this case statements in Wikidata were made.

The outward appearance is that Wikipedia and Wikidata are two distinct projects. Wikidata however has always included data from Wikipedia and there has always been a realisation that Wikipedia in its turn could benefit from Wikidata; generating category entries should be possible for instance.

When you consider the immediate future of the Wikimedia projects, Commons will be wikidatified. One part of the information that is directly related to GLAM activities is registering the museums that include an artist in their collection. This is applicable for many artists that are part of the Black Lunch Table including Mrs Hassinger. So the question is; should we include such information in Wikidata and how should we do this?
